There's an update from April, after 2 years of silence!
It's in Japanese, which I can't read, so I have absolutely no idea what it means.
The discography hasn't been updated (Maxi On's still the most recent release listed), so presumably whatever it says, it's not "There is a new album out!" And since it's been about 8 months, presumably it's not "She's in the studio now working on a new album!" because I'd figure it'd be out by now. (Not necessarily, I suppose, but it does make that less likely.)
So... yeah. Anyone here know Japanese and can translate the news?
